So I just checked out a 15" 2.6 i7 tMBP at a local Mac store and was comparing it to my mid-2012 2.6 i7 rMBP with 1TB SSD (after-market) upgrade. I should mention that my machine's SSD only had 30GB available of the 960GB it has, the rest is used. One thing I noticed was that the 2016 tMBP seemed to be launching apps noticeably slower than my older rMBP. I did a few shutdown / restart tests on both machines to see if I was imagining things and my 2012 rMBP significantly out-performed the 2016 model in both shutdown and restart times. I then ran Blackmagic Disk Speed Test to verify what I observed and, once again, I found that my 2012 rMBP was showing better read and write speeds than the 2016 tMBP. My 2012 showed around 505 MB/s read and 425 MB/s write speeds vs the 2016 scoring around 10-15% slower in both tests. This surprised me because every review I've read / watched on the new tMBPs said how blazing fast the new SSDs are, and part of my reason for wanting a newer 2016 tMBP is to get a 2TB unit, both for the added space and supposed performance improvement. Thinking it may have been a bad unit, I tried the test on a 13" 2016 MBP without the touch bar and the disk speeds were a little slower even than the 15" 2016 tMBP. Unfortunately the store only had 256GB SSD models on demo, none with the bigger SSDs. I don't know if this is a problem specific to the 256GB SSDs or whether all the 2016 SSDs are really not all that they're made out to be. Could owners with the 2016 MBPs please share what speeds they're seeing on Blackmagic Disk Speed Test, just for comparison? Don't forget to mention machine specs when you do. Thanks. I'm attaching a screenshot of Blackmagic Disk Speed Test taken on my 2012 rMBP. TL;DR 2012 retina MacBook Pro upgraded SSD is faster than supposedly super fast 2016 MacBook Pro SSD.
